1 HP 230 V Sewage Pump

The Zoeller D293 is a 1 HP submersible sewage pump built for 230 V single-phase supply. Its cast-iron body and impeller handle solids up to 2 in diameter. A hermetically-sealed, oil-filled motor and carbon-ceramic shaft seal protect internal components. The integral vertical float switch turns the pump on at 14 3/4 in and off at 5 in liquid level.

Residential and Light-Commercial Waste

This pump suits homes or small businesses that need to lift sewage from a basin to a gravity sewer or septic system. The 2 in discharge and 24 in minimum sump diameter match standard residential pits. Installations requiring higher flow at greater head, three-phase power, or a smaller basin should evaluate other models.

Vertical Float Switch Levels

The integral vertical float switch provides fixed actuation points: on at 14 3/4 in and off at 5 in. These levels determine the minimum basin depth and the pumping cycle volume. Buyers must verify that the pit depth and required cycle match these exact switch settings.

Questions about this item

How do I set the vertical float switch so the pump turns on at 14 3/4 in and off at 5 in without the tether snagging?

Mount the pump vertically in a pit at least 24 in wide, route the integral float cord clear of the discharge pipe, and verify the on point at 14 3/4 in and off point at 5 in before backfilling.

Which wear items on the carbon-ceramic shaft seal and cast-iron impeller should I plan to replace after extended service?

The carbon-ceramic shaft seal and cast-iron impeller are the primary wear parts; inspect the seal for leaks and the impeller vanes for erosion during annual maintenance.

At what head does the 1 HP motor hit its thermal limit during continuous 230 V operation?

At 40 ft of head the flow drops to 51.0 gpm and the motor draws 10.20 A, indicating the practical limit for sustained running without overheating.
